Definitions
- the invention relates to elasticized composite fabrics for use in disposable absorbent articles and to the components of these fabrics.
- Disposable diapers are composite absorbent articles that are designed to be worn about the lower torso as undergarments by incontinent persons and by infants and young children prior to toilet training.
- Disposable diapers typically include a liquid impervious back sheet as the outer surface of the diaper, a liquid pervious topsheet as the inner surface of the diaper for placing adjacent the skin of the wearer, and an absorbent core placed between the topsheet and the back sheet for absorbing urine and other liquids.
- the invention provides a nonwoven web of multipolymer fibers, a method for making the web, a composite elastic laminate that includes the web and an elastic component, and a disposable absorbent article that includes the composite elastic laminate of the invention.
- the laminate is suitable for use in disposable absorbent articles, including use as elasticized side panels in diapers that are subjected to incremental mechanical stretching to activate the topsheet and the back sheet.
- the laminate is also suitable for use as a discrete stretchable member that is attached to the side edges of the main body of a garment, including a diaper, and has exceptional cloth like hand.
- the multipolymer fibers are highly elongatable.
- the web can be stretched to orient the fibers in one or the other of the machine direction or the cross machine direction to substantially increase the elongation of the web at peak load in a direction perpendicular to the elongation of the web and to also increase the tensile strength in the web in the direction of elongation.
- the web can be stretched in the absence of heat treatment, which is to say that the web can be stretched at a temperature from about 35 to 150 degrees Fahrenheit. Normally, the web will be stretched at an ambient temperature from about 65 to 110 degrees Fahrenheit.
- the web Prior to stretching, the web will typically have an elongation at peak load in at least one of the machine direction or the cross machine direction of at least 70 percent.
- Mechanical stretching permanently elongates the web and develops a high degree of stretchability in the direction perpendicular to the elongation of the web.
- the elongation at peak load in the direction perpendicular to the direction of stretch is increased by a factor of at least about 2:1, and in a more specific aspect of the invention, by a factor of more than 4:1.
- Composite elastic fabrics made with the nonwoven web of the invention can typically be stretched to the elastic limit of the elastic component since the web is usually capable of stretching farther.
- the web is substantially strengthened and does not undergo thinning and damage during incremental mechanical stretching.
- the multipolymer fibers can be formed with the different polymers in discrete structural domains or from a blend of polymers that are miscible, immiscible, or a blend of miscible and immiscible polymers.
- a blend can also be used as one component in a multipolymer fiber formed of discrete structural domains.
- the polymers are immiscible and are blended to form a dominant continuous phase and at least one dispersed phase.
- Exemplary immiscible polymers include polyethylene, including linear low density polyethylene and polypropylene. These polymers are normally considered to be inelastic. Either polymer can be the dominant continuous phase.
- the blend can also include an elastic component.
- the preferred blend includes a third component that is at least partially miscible with the two phases and gives the blend highly elongatable characteristics.
- An example of a suitable blend for forming multipolymer fibers is: isotactic polypropylene present in an amount of about 65 to 80 percent by weight based upon the weight of the blend; linear low density polyethylene present in an amount from about 1 to 5 percent by weight based upon the weight of the blend; and a block or grafted polyolefin copolymer or terpolymer having at least a portion of the chain thereof miscible with the isotactic polypropylene and wherein the block or grafted polyolefin copolymer or terpolymer is present in an amount from about 15 to 30 percent by weight based upon the weight of the blend.
- Examples of such a block or grafted polyolefin copolymer are the commercially available CatalloyTM copolymers available from Montell .
- the multipolymer fibers can be spunbond continuous filaments, carded discontinuous staple fibers and meltblown fibers. Normally, the web will be prepared from continuous spunbond filaments.
- the invention comprises a composite fabric that has at least one layer of an elastomeric component bonded to at least one layer of the nonwoven web described above.
- the elastomeric component can be selected from elastic strands, scrim, elastic films, and breathable elastic films.
- the fabric can be gathered in the direction in which the nonwoven web component previously was permanently elongated by mounting the web to the stretched elastic component and then relaxing the elastic component in the manner taught in U.S. Patent No. 5,114,781.
- the invention comprises a method for substantially increasing the elongation at peak load of a bonded nonwoven web wherein a web of multipolymer fibers is prepared and then stretched in one of the machine or cross machine directions at a temperature from about 35 to 150 degrees Fahrenheit to permanently elongate the web.
- the elongation at peak load of the web in the direction perpendicular to the stretch direction is substantially increased.
- the method can include the additional step, if desired, of stabilizing the web against retraction of the fibers by lightly bonding the stretched web, normally through the application of heat and pressure.
- the invention provides a composite elastic fabric with cloth like hand and good cover characteristics that is suitable for use in disposable absorbent articles, especially as elastic side panels in diapers, either as discrete members attached to the main body of the garment or in laminates mounted between the topsheet and back sheet .
- the nonwoven web component of the composite fabric has the strength to perform well in incremental stretching.
- the web can be permanently elongated in one direction to impart substantial ability to stretch in a direction perpendicular to the direction of elongation, all in the absence of heat treatment.
- Figure 1 is a perspective view of a portion of a bonded nonwoven web of multipolymer fibers prior to stretching in accordance with the invention
- Figure 2 is a perspective view of the nonwoven web of Figure 1 after the nonwoven web has been permanently elongated in accordance with the invention and stabilized by application of light bonding;

- Figure 13 is a photomicrograph at 2OX magnification of a section through a pointbonded spunbond nonwoven web of multipolymer continuous filaments after the web has been stretched in accordance with the invention and showing a pointbond that has become vertically orientated in the fabric as a result of the stretching.
- Figure 1 is a perspective view of a portion of a bonded nonwoven web 20 prepared from multipolymer fibers.
- the nonwovens may be carded, spunbonded, wet laid, air laid or meltblown. Normally, prior to stretching, the web will have an elongation at peak load in at least one of the machine direction or the cross machine direction of at least 70 percent.
- the nonwoven fibrous web is a spunbonded nonwoven comprising multipolymer spunbond continuous filaments. The filaments are bonded together at discrete bond sites 22 distributed throughout the fabric to form a unitary, coherent nonwoven web.
- the multipol mer fibers of the invention are predominantly formed from polymers that normally are considered nonelastic.
- Useful polymer combinations for use in the practice of the invention are taught in published PCT International Patent Application PCT/US95/15257, filed November 22, 1995, and entitled Extensible Composite Nonwoven Fabrics. The contents of this application and the teachings contained therein are hereby incorporated . by reference in their entirety.
- multipolymer fibers includes staple and continuous filaments prepared from blends of two or more polymers and from two or more polymers present in discrete structural domains in the fiber.
- polymer is used in a general sense, and is intended to include homopolymers , copolymers, grafted copolymers, and terpolymers.
- blend is also used generally herein, and is intended to include immiscible and miscible polymer blends.
- the polymers are considered to be “immiscible” if they exist in separate, distinct phases in the molten state; all other blends are considered to be “miscible.” It is understood that varying levels of miscibility can exist, and are also intended to be within the scope of this invention.
- Blends with more than two polymers may also be utilized, including those with three or more polymer components. Both immiscible and miscible polymers may be added to a two component blend to impart additional properties or benefits with respect to blend compatibility, viscosity, polymer crystallinity or phase domain size. Since the polymers employed in the invention will undergo extrusion, stabilizers and antioxidants are conventionally added to the polymer. Other additives may also be added in accordance with the present invention. For example inorganic additives such as titanium dioxide, talc, fumed silica or carbon black.
- the polymer resin may also contain other additives, such as other polymers, diluents, compatibilizers, antiblocking agents, impact modifiers, plasticizers, UV stabilizers, pigments, delusterants, lubricants, wetting agents, antistatic agents, nucleating agents, rheology modifiers, water and alcohol repellents, and the like. It is also anticipated that additive materials which have an affect on processing or product properties, such as extrusion, quenching, drawing, laydown, static and/or electrical properties, bonding, wetting properties or repellency properties may also be used in combination with the blend. In particular, polymeric additives may also be used that impart specific benefits to either processing and/or end use.
- the multipolymer fibers are normally formed of a polymer blend composed of two or more polymers .
- the polymers of the blend can be miscible, immiscible, or a combination of miscible and immiscible polymers.
- the polymers may exist as a dominant continuous phase and at least one substantially discontinuous dispersed phase.
- other polymers may also be present which are either miscible in one, or the other, or both polymer phases .
- the multipolymer fibers are formed of a polymer blend composed of a dominant continuous phase, and at least one polymer, having low mutual affinity with the dominant phase, dispersed therein, and at least one additional polymer which is at least partially miscible in one or the other or both continuous and dispersed polymer phases. If the one additional polymer is miscible in the dominant phase, and effectively reduces its crystallinity, it is believed that the improved extensibility observed in the resulting composites may be due to an "impact-modifying ' effect. If the one additional polymer has an affinity for both polymers, or serves to lower the surface energies between the two phases, it is believed that the improvement observed in the composite extensibility is due to a compatibilization effect.
- the blend must ultimately form filaments or fibers, which when formed into webs and composite structures exhibit the properties described by the invention, meaning low fuzz and good elongation.
- the multipolymer fibers may comprise from 1 to 50 percent by weight polyethylene and from 99 to 50 percent by weight polypropylene. Fabrics formed from such blends exhibit low fuzz and good elongation.
- the composite fabric may include a coherent, extensible nonwoven web ' formed of fibers of a polyethylene and polypropylene blend where the polyethylene is present in the range of 1% to 10% and the polypropylene is present in the range of 90% to 99% by weight.
- the multipolymer fibers may include a dominant amount of a polypropylene, such as isotactic polypropylene, a small amount of a polymer having low mutual affinity with the dominant polymer, such as polyethylene, and an additional third polymer which either reduces crystallinity and/or compatibilizes the blend. What results is a softer web, with extremely high extensibility.
- Preferred multipolymer fibers according to this embodiment may comprise greater than 50 percent by weight polypropylene, 1 to 10 percent polyethylene, and 10 to 40 percent of the third polymer.
- Suitable additional third polymers include polypropylene copolymers and terpolymers such as the commercially available CatalloyTM copolymers available from Montell . These resins are characterized by having the comonomer(s) exist to some degree in blocks, and wherein at least some portion of the polymer chain is miscible with one or the other, or both, dominant and dispersed polymer phases.
- Other suitable polymers are the ReflexTM flexible polyolefins from Rexene . These crystallinity reducing resins are characterized as having atactic segments present in the polymer chain, such that the "tacticity" of the polymer is affected.
- Another class of useful and advantageous products according to this aspect of the invention employ multipolymer fibers formed of a polymer blend comprised of a soft, extensible polymer phase, and at least one additional polymer having low mutual affinity with the soft, extensible phase, such that it modifies either the rheological, mechanical, and/or thermal properties of the fibers in a way that improves processability (e.g. melt spinning), bonding and/or abrasion resistance while maintaining high extensibility.
- the soft, extensible phase is present as a dominant, continuous phase.
- polyethylene can be used as the soft, extensible dominant phase and a polypropylene as the additional modifying polymer.
- the additional polymer is added in a small proportion relative to the dominant phase.
- the additional polymer exhibits higher viscosity relative to the dominant phase. Blending a relatively small proportion of the higher viscosity polypropylene with the soft, extensible polyethylene imparts greatly increased abrasion resistance to a nonwoven fabric formed from the polymer blend, without significant adverse effect upon other important fabric properties, such as extensibility, softness, tensile strength, etc. The spinnability of the polyethylene is also improved by the presence of the additional polypropylene.
- the fibers preferably comprise between 2 to 50 percent by weight of the propylene polymer, e.g. 3% ethylene-propylene copolymer, and 98 to 50 percent by weight of the soft, extensible polymer, e.g. polyethylene.
- the fiber composition may range from 5 to 40 percent by weight propylene polymer, and most desirably between 5 to 25 percent by weight propylene polymer and 75 to 95 percent by weight polyethylene.
- fiber compositions of from 5 to 25 percent by weight propylene polymer.
- a most preferred embodiment contains 5 to 25 percent by weight of ethylene- propylene copolymer or terpolymer and 75 to 95 percent by weight linear low density polyethylene.
- the lower melting polyethylene is present as a substantially continuous phase in the blend and the higher melting propylene polymer is present as a discontinuous phase dispersed in the polyethylene phase.
- the polyethylene and polypropylene components are combined in appropriate proportional amounts and intimately blended before being melt-spun. In some cases sufficient mixing of the polymer components may be achieved in the extruder as the polymers are converted to the molten state. In other cases, more dynamic mixing may be required.
- LLDPE should have a melt index of greater than 10, and more preferably 15 or greater for spunbonded filaments. Particularly preferred are LLDPE polymers having a density of 0.90 to 0.945 g/cc and a melt index of greater than 25.
- suitable commercially available linear low density polyethylene polymers include those available from Dow Chemical Company, such as ASPUN Type 6811 (27 MI, density 0.923), Dow LLDPE 2500 (55 MI, 0.923 density), Dow LLDPE Type 6808A (36 MI, 0.940 density), and the Exact series of linear low density polyethylene polymers from Exxon Chemical Company, such as Exact 2003 (31 MI, density 0.921).
- Various polypropylenes made by processes known to the skilled artisan may also be employed.
- the polypropylene component can be an isotactic or syndiotactic propylene homopolymer, copolymer, or terpolymer.
- examples of commercially available propylene homopolymers which can be used in the present invention include SOLTEX Type 3907 (35 MFR, CR grade), HIMONT Grade X10054-12-1 (65 MFR), Exxon
- Type 3445 35 MFR
- Exxon Type 3635 35 MFR
- AMOCO Type 10-7956F 35 MFR
- Aristech CP 350 J melt flow rate approximately 35
- Examples of commercially available copolymers of propylene include Exxon 9355 which is a random propylene copolymer with 3% ethylene, 35 melt flow rate; Rexene 13S10A, a 10 melt flow rate random propylene copolymer with 3% ethylene; Fina 7525MZ, an 11 melt flow rate 3% ethylene random propylene copolymer, Montel EPIX 30F, a 1.7% ethylene, 8 melt flow rate random copolymer of propylene.
- the preferred melt flow rate is greater than 20.
- the preferred melt flow rate is less than 15 and most preferably less than 10.
- the multipolymer fibers of the web may be bicomponent or multicomponent fibers or filaments.
- the term bicomponent or multicomponent refers to the existence of the polymer phases in discrete structured domains, as opposed to blends where the domains tend to be dispersed, random or unstructured.
- the polymer components can be configured into any number of configurations including sheath-core, side-by-side, segmented pie, islands-in- the-sea, or tipped multilobal .
- a coherent extensible nonwoven web can be made, for example, from a sheath- core bicomponent fiber having a polyester core and a polyethylene sheath, or the sheath or core can comprise a blend as discussed above.
- the extensible web can comprise a single web containing a combination of spunbonded filament and meltblown fibers or a combination of carded staple fibers and meltblown fibers .
- the extensible nonwoven web in all embodiments in accordance with the present invention, is characterized by having high surface abrasion resistance and high elongation.
- the surface abrasion resistance of the web may be conveniently measured objectively by physical tests which are standard in the industry, such as the Taber abrasion test as defined by ASTM Test Method D-3884-80.
- Extensible webs useful in the composite fabrics of the present invention are characterized by having a Taber abrasion value (rubber wheel) of greater than 10 cycles.
- the webs are further characterized by having an elongation at peak load (ASTM D-1682) , prior to stretching, in either the machine direction (MD) or in the cross-machine direction (CD) or both of at least 70 percent, more preferably at least 100 percent, and most desirably at least 150 percent.
- the multipolymer fibers of the web are of relatively fine diameter, typically 10 denier or less.
- the web shown in Figure 1 has been bonded so that it can be stretched, but has not yet been stretched.
- the web shown in Figure 1 has been point bonded by passing the web through a calender nip in which one of the calender rolls is smooth and one of the calender rolls has a patterned surface for applying the bonding pattern.
- Intermittent point bond regions 22 are formed wherein the web is bonded.
- the discrete bond sites comprise areas where the fibers have been fusion bonded together. It should still be possible to trace an individual filament through the bond site if the bond site is not overbonded.
- the fused regions cover between 6 and 30 percent of the area of the web, more preferably 8 to 20 percent, and most preferably 12 to 18 percent of the web is covered.
- the filaments are allowed to elongate throughout the full extent of stretching while the strength and integrity of the fabric is maintained.
- the skilled artisan should recognize that there are myriad other ways to bond a web sufficiently to enable the web to be stretched. While thermal point bonding is most preferred for spunbond, carded, and other webs, any thermal, chemical, or mechanical bonding treatment may be used to form a coherent web structure .
- Figure 2 represents the nonwoven web 20 of Figure 1 that has been permanently elongated by mechanical stretching in either the machine direction or the cross direction. It should be understood that the web can be subjected to stretching in either of the cross machine or machine direction to achieve the benefits of the invention, but not both. Normally, the web is stretched in a direction having an elongation at peak load of at least 70 percent. It should be recognized that this property could be met in one of or both the machine and cross machine directions .
- the web has been stretched and permanently elongated by the stretching at a temperature of between about 35 to 150 degrees Fahrenheit.
- the web normally is elongated in the absence of heat treatment at an ambient temperature, which typically varies from about 65 degrees on a relatively cold day to about 110 degrees on a hot summer day, and most typically is on the order of about 65 to 85 degrees.
- the nonwoven web develops extraordinary elongation at peak load in the direction perpendicular to the direction of stretch.
- Elongation at peak load can be at least about
- the fabric is capable of stretch well beyond the original dimension of the fabric in the direction perpendicular to the stretch direction.
- the tensile strength of the webs in the direction of orientation of the filaments which is normally the stretch direction, is greatly increased.
- the ratio of tensile strength of the 'web in the direction of orientation of the fibers to the tensile strength of the web in the other direction is at least about 10:1 and can be increased to at least about 16:1.
- a further characteristic of the web is high extensibility at low force.
- the nonwoven web has an elongation in one direction, which is the direction perpendicular to the stretch direction, of at least 70% when a load is applied to the web in that direction that is less than or equal to about 300 grams force per inch.
- a force of about 300 grams force per inch or less is about the force that the consumer feels on the wrist when using a fabric in accordance with the invention.
- the web can be prepared wherein the elongation of the web in the direction perpendicular to the stretch direction is at least 100% to 350% at a load of less than 300 grams force per inch. Table 2, below, shows examples at 100%, 200%, and 350% elongation at loads of less than 300 grams force per inch.
- the filaments that are not oriented in the stretch direction prior to stretching become oriented in the stretch direction as a result of the stretching, but are either not elongated or are only partially elongated.
- This feature is graphically illustrated in the photomicrographs shown in Figures 10 and 11, which are at 5 and 10X magnification, respectively, and show a multipolymer continuous filament pointbonded spunbond nonwoven web that has been stretched in the machine direction. A substantial number of the filaments can be seen to be oriented in the machine direction, which is the direction of stretch. In any event, the fabric becomes stretchable in the direction perpendicular to the stretch direction to an extent beyond the prestretched dimension in that direction.
- the fabric also develops a z-direction axis and becomes thicker as the fabric is stretched and the dimension in the direction perpendicular to the stretch direction becomes smaller.
- Figure 13 shows in a photomicrograph at 2OX magnification the distorted, deformed point bonds of a non-planar configuration embedded in the web between opposite surfaces of the web. These bond sites have been pulled into the body of the spunbond nonwoven web and extend in the Z-direction axis. Prior to stretching, the pointbond was horizontally oriented as shown in the photomicrograph of Figure 12, which is also at 20X magnification. Increase in the thickness of the nonwoven web due to stretching can also be seen by comparing Figures 12 and 13.
- the fabric has been lightly bonded after stretching with a plurality of point bond sites 24 in a pattern reminiscent of cross laid bricks.
- the point bond sites 24 include film-like fused regions that are generally planar and are parallel to the surface of the web and lie at the web surface.
- the stretched fabric was bonded by passing through a calender nip at light pressure and low heat to stabilize the web and to substantially preclude retraction, since a small about of elastomeric polymer is used in the fibers of which the fabric is made.
- the bonding is graphically illustrated in the photomicrographs of Figures 10 and 11. It should be recognized that a wide variety of suitable bonding patterns are available and should provide equivalent performance in the practice of the invention.
- the bonding should be enough to stabilize the web against retraction of the fibers after elongation to the desired extent, but not so great as to preclude stretching in the direction perpendicular to the stretch direction, for which the fabric is designed. It is usually advisable to lightly bond the web after stretching when the web will be rolled rather than supplied directly to a laminator for lamination with an elastomeric component. The elastomeric component of the web can cause the web to retract in the roll if the web is not lightly bonded.
- the fabric illustrated in Figure 2 can be stretched in any of several ways known to the skilled artisan. The fibers normally are extruded, collected on a web forming surface, bonded, and stretched in line.
- the nonwoven web is rolled prior to stretching and stretching is accomplished as a separate operation. Stretching in the cross machine direction normally is accomplished using a standard tenter frame. It should be recognized that other methods and apparatus can be used to stretch the nonwoven web in the cross direction, although not necessarily with equivalent results. For example, the web can be incrementally stretched in the cross direction using intermeshing or interdigitating rollers. Typically, the web is stretched in the machine direction. One method of machine direction stretching is schematically represented in Figures 3 and 4. It should be recognized that other methods and apparatus can be used to stretch the nonwoven web in the machine direction, although not necessarily with equivalent results. For example, the web can be incrementally stretched in the machine direction using intermeshing or interdi ' gitating rollers.
- a nonwoven web of multipolymer fibers 20 prepared from the polymer combinations discussed above is supplied from a roll 26 called the unwinder.
- the web passes around three rolls 28, including a load cell and two idler rolls, arranged at the corners of a triangle for sensing and adjustment of web tension prior to stretching the web.
- the web is stretched by passing through a series of rolls in three successive S-wrap stations 30, 32, and 34.
- the bottom roller 36, 38, 40 is driven and the top roller and bottom roller form a nip 42, 44, 46 that applies light pressure to the web that does not bond the web, but provides sufficient grip that the web can be stretched between the subsequent sets of S-wrap rollers.
- Subsequent S-wrap roll stations are driven at increasing speeds to apply increasing tension to the web between each set of rollers in the S-wrap station sufficient to stretch the web.
- Figure 4 represents a partially broken away top perspective view of a portion of the schematic of Figure 3 taken along line 4-4.
- the reduction in the cross direction of the width of the web is shown as the web is stretched in the machine direction, first as the web passes between the first and second S-wrap stations 30, 32, and second as the web passes between the second and third S-wrap stations 32, 34.
- the width of the web is the cross machine direction is considerably reduced between the first S-wrap station and the third.
- the web is permanently elongated.
- the filaments in the outer portions of the web tend to be elongated faster than the filaments located in the center of the web. For this reason, the distance between the first S-wrap station and the second should be sufficient to provide that the filaments in the center of the web are also permanently elongated to the desired extent.
- rollers can be used to stretch the web in the machine direction. Rollers can be used in the omega configuration to apply sufficient tension to the web to permanently elongate the web. After stretching, the now permanently elongated web is treated in a manner believed to be known to the skilled artisan to improve its uniformity by passing over first and second bow rolls 48, 50 to flatten the web and take out wrinkles .
- the web is then lightly bonded to stabilize the web against retraction prior to tension adjustment 57 and rolling the web on a winder 58 for supply to a line for making disposable absorbent articles.
- the web can be bonded by passing through a calender nip 52 formed between two rollers 54, 56.
- the calender nip should be operated at light pressure and low heat .
- Examples 1 and 2 are were both prepared from the same control fabric at different line conditions. The relatively slight differences in the values obtained for the physical characteristics of these webs is due primarily to differences in line conditions.
- the control fabric had similar physical characteristics in the machine direction as in the cross machine direction, as is reflected by the ratio of the tensile strength in the machine direction to the tensile strength in the cross direction of 2.82.
- a value of 2.82 means that the nonwoven control web was relatively square in its properties.
- the balance of properties is also reflected by the MD/CD elongation ratio, which reflects that the fabric is stretchable and permanently elongatable in either the cross direction or the machine direction.
- a nonwoven web stretched as shown in Figures 3 and 4 is illustrated in Figure 5 in an exploded view of an elastic fabric laminate of the invention 62.
- Elastomeric strands 60 are placed between two nonwoven webs 20 ( Figure 2) and the laminate is bonded, normally by application of a hot melt or other suitable adhesive.
- the laminate can be prepared with a single nonwoven web on one side to produce a two layer laminate rather than a three layer laminate, if desired.
- the fabric of the invention has sufficient cover provided by Z axis development to preclude substantial glue bleed-through.
- the elastomeric strands are oriented to stretch in a direction perpendicular to the direction in which the nonwoven webs were permanently elongated. The webs were stretched in the machine direction as shown in Figures 3 and 4, and so the elastomeric fibers are oriented to stretch in the cross machine direction.
- the fabric laminate is elastic in the cross machine direction and recovers substantially all of the distance it is stretched when stretched below the elastic limit of the elastomeric strands .
- the nonwoven webs of the invention can stretch in the cross machine direction to many times the distance of the initial width of the nonwoven web prior to elongation. Typically, the strands are bonded to the web directly, without being placed under tension or elongated. If it is desired that the fabric laminate stretch in two directions, then the elastic component that is sandwiched between the nonwoven webs of the invention should provide for stretch in two directions. The nonwoven web can then be applied to the elastic component so as to form gathers when the elastic component is relaxed that can allow stretch in the direction in which the web was permanently elongated.
- the web can be applied to tensioned elastomeric strands so that the gathers form when the strands are relaxed.
- the laminate can then be stretched and will exhibit recovery to the extent allowed by the gathers.
- a wide variety of elastic components are suitable for use in the practice of the invention.
- Elastomeric strands, scrim, or elastomeric film, including perforated and nonperforated films and barrier or moisture vapor transmitting films, are all suitable for use, depending on the results desired.
- Elastomeric strands and scrim tend to produce fabrics with enhanced breathability as compared to films and are preferred in countries of high heat and humidity. Films are preferred in more arid climates since they are cheaper.
- the elastic laminate of the invention is suitable for use as an elastic fabric having highly desirable cloth like characteristics.
- the laminate is suitable for use in a variety of disposable absorbent articles.
- the laminate is useful as a stretch side panel in diaper construction.
- a disposable diaper 64 is represented in Figure 6 that incorporates a pair of elastic side panels 62 made from fabric laminate of the invention.
- the diaper is shown in plan view having the outer surface back sheet 66 facing the viewer. Internal structure is shown in outline by the dashed lines.
- the diaper includes a water pervious topsheet 65 ( Figure 7) , a water impervious back sheet 66, and an absorbent core 68 that typically comprises wood pulp or other absorbent material and typically includes superabsorbent polymer powder.
- a surge layer may be used to provide a holding area for urine in the front waist region for the time required for the superabsorbent polymer to take up the urine after strikethrough.
- the diaper includes front and rear waist bands 70, 72, which typically are elasticized.
- the elastic side panels of the invention 62 are laminated into the diaper structure between the back sheet and the topsheet. As shown, the anchored ends of the securing tabs overlap somewhat the elastic side panels. The side panels are oriented in the diaper to provide transverse stretch, which is in the direction of tension on the securing tab, to improve the fit of the diaper, even under conditions where the wearer is active.
- the composite When made with elastic scrim or elastomeric fibers, the composite typically has good breathability, but also contributes to fluid barrier outside the strikethrough and absorbent region.
- Elastic film can also be used as described in Weil et al. U.S. Patent No. 5,242,436, which illustrates a diaper construction having an elastic side panel therein.
- Placement of the elastic side panel of the invention into the diaper is represented in Figure 7. As shown, the laminate is placed between the top sheet and the back sheet so as to provide some elasticity to the ear region in the direction of pull of the securing tab.
- the fabric of the invention provides a soft, cloth like hand and excellent cover, and yet is exceptionally strong.
- the topsheet and the back sheet typically are constructed of inelastic materials that do not exhibit stretch and recovery and it normally is necessary to treat the diaper construction in the region of the elastic side panel so that the topsheet and back sheet will be activated to move with the elastic side panel.
- a suitable method for mechanically incrementally stretching in the cross direction the composite of the top sheet, elastic stretch laminate of the invention, and the back sheet is described in Weil et al. U.S. Patent No. 5,242,436.
- nonwoven fabric laminate of the invention can be used in the manner described in U.S. Patent Nos. 4,981,747 and 5,114,781 as a fabric that is secured to the securing tab and mounted onto the diaper back sheet rather than laminated within the diaper between the topsheet and the back sheet.
